A single storage drive failure does not cause a data failure if the storage drives are configured as a RAID (level 1 or higher). The storage drive can be removed and a new storage drive inserted, which is then automatically rebuilt with data from the rest of the array with no need to reconfigure the RAID parameters. If a hot-spare was configured to replace the failed drive, the new replacement storage drive should be automatically configured as the new hot-spare.
For instructions for configuring RAID on the server, refer to Configuring Server Drives for OS Installation in Oracle Server X5-4 Installation Guide.
If optional NVMe drives are part of the RAID, special replacement instructions must be followed to prevent an operating system crash. See:
